IM PROV EMENT 1 N CAR-HEATING APPARATUS.

Specification forming part of Letters Patent No. 214,532, dated April22, 1 879 application filed September 26, 1878.

To all whom it may concern- Be it known that I, JOHN A. STRAIGHT, ofAlbion, in the county of Orleans, and in the State of New York, haveinvented a new and useful Improvement in Gar-Heating Apparatus, of whichthe following is a specification.

The drawing is a plan view, modified, to more clearly exhibit theconstruction and arrangement of the parts.

i which, also, a positive movement of the steam and condensation-wateris obtained throughout an extended length of pipe; and, second, in thecombination, with a proper system of heating-pipes, of an injector,located as described, and suitable means for connecting anddisconnecting the same from the pipesystem. I

In the drawing is represented a plan view of my invention, with theposition of some of the parts modified, to show more clearly theconstruction and arrangement.

To enable others skilled in the art to make and use my invention, 1 willproceed to describe the same fully.

A represents a pipe, leading from the boiler at any proper point, whichextends in a rearward direction to the flexible coupling-tube D, withwhich it is connected, as shown. B represents a pressure-reducer of anyproper construction, located in this pipe, by means of which theboiler-pressure may be reduced to that which is proper for heatingpurposessay, from one hundred and thirty pounds to fifteen pounds, orless.

E represents a coupling-tube, united to the fellow-tube D, as shown, bymeans of which connection is made with the pipe F.

A pipe, F, and proper couplings are provided for each car in the train,in the manner well understood.

G represents a return-pipe, similar to the pipe I with which it isconnected by proper couplings, by means of which the steam andcondensation-water in the pipesystem are conveyed back through propercouplings and the pipe H to the boiler-tank, as shown.

I represents an injecting-nozzle, of any proper construction, by meansof which the steam and condensation-water in the pipe-system may beforced into the boiler-tank. J

' represents a branch pipe having a stop-cock,

by means of which the pipe-system is adapted to discharge into theboiler-tank without the use of the injector.

The operation will be readily understood. Steam having been admittedinto the system from the boiler, the same is caused to circulatethroughout the entire length of the system, and to discharge, togetherwith the condensation-water, into the boiler-tank.

The injector may be regularly employed to insure positive circulationbut, if desired, its use at times may be omitted.

I am aware that ejectors of various devices are used for feeding steam-boilers; but I do not claim the ejector for the purpose of feeding, nordo I use it primarily for that object, my purpose being to provide anefficient means of removing water of condensation from extendedsteam-heatin g pipes without employing the trap hitherto deemednecessary, and without discharging the water upon the ground, as hasbeen customary.

Having thus fully described my invention, what I desire to secure byLetters Patent is 1. In combination with a proper system ofheating-pipes, an injector, located at the discharge end of the system,for the purpose of drawing off the waste steam and condensationwater,substantially as and for the purpose set forth.

2. In combination witha proper system of and couplings, the injector Iand the branch pipe J, as and for the purpose described.

JOHN A. STRAIGHT.
